Title: Improvements in Electric Circuit Closing Contacts.
Inventor: MACKENZIE JOHN WILLIAM
IPC: H01H50/64
Filed: 1909-06-28
Granted: 1910-05-19
Abstract: 15,075. Mackenzie, J. W., [Sundh Electric Co.]. June 28. Electro-magnetic switches.-Relates to alternating - current electromagnetic switches of the type wherein the core or armature hasa lost-motion c nnexion with a toggle linkage which is forced over the dead-centre to close the switch contacts and to relieve the core or armature of the weight of the switch part?, for the purpose of preventing the vibrations of the core from being communicated to the contacts. The invention consists in disposing the parts so that the central pin 56 of the toggle linkage 54, 55 lies directly above the operative end 14 of the core 9 and directly below a fixed stop 58. The core is thus not allowed to touch the fixed stop itself, but, after the up-stroke has been performed, sinks back to a position where it is magnetically supported. The core 9 of the electromagnet 6 is clamped to a pair of brass bars 10, 11, which slide in recesses in fixed guide-plates 16. The bars at their lower ends are fastened to a block 12 and at their upper ends to a circular cap 14 provided with a slotted bar 20 embracing the toggle 56 and moving it up and down. The toggle links 54, 55 are linked at their free ends to levers 52, 53 which have short bent arms carrying the contact springs 41, 30 and also sleeves and clamping-nuts to attach terminal wires A, C. Contact-pieces 42, 31 at the ends of the contactsprings are adapted to meet carbon blocks 43, 44, attached to terminal wires B, D. Blocks 18, 59 of rubber or other material are attached to the core and the fixed stops to cushion the blow of the toggle pin.

Granted: 1910-04-28
Abstract: 30,170. Pauly, A. A. Dec. 24. Moulds. - Cement building- blocks &c. a r e moulded in apparatus in which the objects formed are moved in a continuous path and subjected to heat until they are sufficiently set to stand alone. The moulding-apparatus comprises a box-like casing 1, having hollow walls 2, 3, and 4 into which steam is led by means of pipes 16 for heating the blocks when formed; hollow cores 6, adjustably mounted in a support 7 and heated by steam from a pipe 14 ; plungers 9, reciprocable lengthways of the core by actuating-bars 10 ; and traverse sectional partition plates or pallets 11, fitting round the core and adapted to be advanced step by step by the plunger with the moulded articles between them. The steam condensing in the core and casing is drained off through vents 15, 19. The front part of the casing 1 is provided with a hinged cover 4<1>, and forms the sides and bottoms of the mould, the ends being formed by two pallets 11 placed on the core at the required length of the block apart with the right-hand pallet immediately below the hinge pin of the cover 4<1> and the plunger 9 in contact with the lefthand pallet. The mould space is first filled with cement, after which the hinged cover 4<1> is lowered and the plunger 9 moved to bring the left-hand pallet beneath the cover hinge pin. The plunger is then withdrawn to its original position, a fresh pallet is placed in contact with it, and a further block is moulded and moved into the casing 1 as before. By this apparatus blocks are intermittently delivered at the right-hand end of the casing 1. Modifications of the invention are shown in which (1) the hinged cover 4<1> is omitted and the mould portion of the casing is solid, the remainder of the casing being made up of flanged sections having internal steam spaces which may be in communication or separate, (2) the bottom of the casing 1 is extended and depressed to receive a carrying-off board to facilitate the removal of the blocks and the upper wall of the casing may be shorter at its outer end to allow a design such as a trademark, rock-face, &c. to be impressed on the upper face of the block by means of a die.

Title: Improvements in Electrically Operated Indicating, Registering and Controlling Devices.
IPC: B61L3/04
Filed: 1910-01-12
Granted: 1910-08-04
Abstract: 827. Soc. d'Electricite "Nilmelior," and Colas, J. E. Jan. 13, 1909, [Convention date]. Electric operation and control.-In electrically-operated indicating, registering, and controlling devices which are actuated automatically at a predetermined time or place, a magneto-electric machine having its armature operated to generate actuating-current, is employed to work the device, together with an interrupter which may act in conjunction with the machine to close the electric circuit when the device is to be operated. The improvements are generally applicable and are described with reference to railway track apparatus. A track contact 18 actuates a lever 12, the shaft 11 of which carries a cam 10 controlled by springs 13, 14 and co-acting with a roller 8 on one arm of a lever 4 attached to the armature shaft 3 of a magneto 1 having magnets 2, the other arm being held by a spring 5. The terminal 19 of the collector 20 is connected to a brush 22 of an interrupter consisting of a disk or sector 23 keyed on a shaft 24, which is provided with a lever 25. The disk has an insulating sector 26, which is normally held in contact with the brush 22 by springs 29, 30, and a conductor sector 27, which is normally in contact with a brush 28 connected to the apparatus 35 to be operated. To operate this device, the lever 12 is turned by contact with the block 18, thus displacing the roller 8 and the armature, upon the return of which current is generated and passes to the device 35 if the lever 25 is at this time operated by the contact 36 to complete the circuit. The lever 25 is arranged to close a little before, and to open a little after, the moment the current is produced. Alternatively, the magnets and the moving contacts may be placed on the track, and the fixed contacts on the vehicle. The apparatus may apply the brakes on the vehicle or register either on vehicle or track.

Title: Improvements relating to Steam Injectors.
Inventor: BROOKE ROBERT GRUNDY
IPC: F04F5/46
Filed: 1910-02-10
Granted: 1910-02-10
Abstract: 1413. Brooke, R. G. Feb. 10, 1909. Giffard injectors; starting and stopping, automatic.-The starting or re-starting of an injector for dealing with hot water or highpressure steam is facilitated by automatically restricting the area of the steam nozzle at first, and by gradually increasing the area as the jet is established. The retractile spindle r is made partly hollow to divert the steam entering at r<1> to a chamber r<2>, where it acts upon the spindle and moves it into the nozzle s. A valve r<3> and seat r<4> ensure the fluid-tightness of the chamber r<2> in the position indicated. A piston s<1> is formed on the spindle, and works in a chamber s<2> connected by a tube s<3> to the injector delivery, so that, when the injector is working, the pressure on the piston withdraws the spindle and allows steam to pass through the full area of the nozzles. A relief port s<4> is provided for the chamber s<2>. A pressure-intercepting valve may be fitted in the pipe joining s<3> and the delivery, as described in Specification 3331/09. In the modification shown in Fig. 4, steam passes by a passage u to a chamber u<1>, and thence through the Venturi passage in the spindle r and passages u<2> leading from the throat u<3> to the chamber u<4>. At starting, the reduced pressure in the chamber u<4> acting on the face u<5> of the piston t<3> together with the pressure on the end of the spindle in the chamber u<1> is sufficient to overcome the delivery pressure acting on the other side of the piston. When the jet is formed, however, the delivery pressure holds the spindle r away from the nozzle s. Among the other modifications in which a Venturi tube is used, one is shown in which the tube is directly open to the steam inlet.

Title: A New or Improved Method of Toning Photographic Prints.
Inventor: TRIEPEL WILHELM
IPC: G03C5/46
Filed: 1910-10-20
Granted: 1911-07-27
Abstract: 24,378. Triepel, W. Oct. 20. Toning.-In toning prints with sulphur compounds, the prints are first converted into silver haloids or silver ferrocyanide, and then are toned in the presence of alkali in a solution of an organic compound of sulphur which does not give off sulphuretted hydrogen in aqueous or faintly alkaline solution. Such organic compounds include thiourea and its derivatives such as thiosinamine, thioamides (for example thiobenzamide) and salts of thiocarbaminic acid (say ammonium dithiocarbamide). A single cold sulphur toning-bath can be used by using such agents for halogenizing the silver as are also effective in the presence of alkalis and by including an ingredient which has an absorbing action as sulphur (say sulphites). A solution is used containing 15 grms. of potassium ferricyanide, 10 grms. of potassium bromide, 4 grms. of sodium sulphite, 2 grms. of thiourea, 2 grms. of sodium hydroxide, and 1 litre of water. For modifying the tone, salts may be added of such metals as form hydroxides that are soluble in alkalis or do not precipitate in the presence of organic compounds, for example, seignette salt. When making tablets, lithium oxide is preferably substituted for the caustic alkali, being less easily transformed into the carbonate than the other caustic alkalis.
